Problem #1: Galaxy S7 Edge touchscreen overly sensitive

Hello, I have a Samsung Galaxy S7 Edge (SM-G935FD), running 6.0.1, BB vers G935FXXU1CPK2, Kernel vers 3.18.14-9519568. I am only operating with a single SIM, only once used two, but have been using one for nearly 12 months now. The problem is that recently, seemingly with no explanation, my phone has become ultra-sensitive on the touch screen and in some instances makes certain apps unusable. I can no longer scroll with the ease i used to, accidentally opening apps, or clicking links without intending to. Not entirely sure if it occurred with the last update or not, but it has been going on for at last two weeks, possibly longer.

I’ve done the *#2663# thing to update the touchscreen software and button firmware, with no effect.

Also tried going through and resetting applications to defaults, no effect. Cleared user data and no change. There are even games that I have had on my phone since four phones ago, that i cannot play as certain buttons don’t respond at all (typically along the curved edges). The game is Defense Zone 2 HD. Are you aware of any recent update issues? is there anything else i can tell you that may help diagnose the issue. I used to love my phone, now am starting to ponder replacing it…please help 😉 Thanks in advance. — Matt

Solution: Hi Matt. There had been scattered reports of a similar problem here and there before so we can’t rule out the possibility that is due to a system update from Samsung. If the issue coincidentally happened after installing a software update or app/app update, you may be able to fix the problem by refreshing the cache partition. This will force the phone to build a new system cache. Here’s how to do it:

Turn off your Samsung Galaxy S7.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’

Once highlighted, you may press the Power key to select it.

Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.

Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

The phone will now reboot longer than usual.

If wiping the cache partition won’t fix the issue, doing away with protective cases or screen protectors may also help. This is obviously only applicable if you are using a case or screen protector in the first place. We highly recommend that you use cases and screen protectors but you want to remove them temporarily for the sake of troubleshooting.

If this workaround won’t change anything at all, also make sure that you check if there are any pending software updates at this time. It may or may not contain a fix for this glitch so it’s worth checking.

If all the above steps are of no help, contact your carrier to report the problem. You may have to eventually seek a replacement if there’s no effective solution that they can provide.

Problem #2: Galaxy S7 screen turns black and shuts down on its own

It’s the 3rd time I’m experiencing this issue, and it seems to happen every month. The first time was in October, then November, and now again in December.

I bought my phone at Mall of America, Samsung Galaxy S7 Edge limited edition USA, and it costed me $900+. I love this phone and tried to live with the problem for a few months, but this problem is affecting my communications, my work, my hobbies, navigation, etc.

The problem started with my phone going black at first. So I pushed the power button to turn it off, but the whole phone screen lights up, sometimes it is green, white, or would stay at purple. The phone gets really really hot. And I can’t turn it off at all.

I did follow the instructions from Thedroidguy, where I had pressed and hold down the power and the volume down buttons at the same time. Nothing can shut the phone off manually. Everytime this problem happened I had to wait for the battery to drain out. The last 2 times, the phone had about twenty something % of the battery left on the phone and that took almost 24 hours before I can reset the phone. But this time, it was at 54% of battery left when my phone begin this issue. Not sure how long I have to wait for this time. Four years ago I switched from iPhone to Galaxy S5 Active and loved it so much. I decided to stay with Samsung, and purchased the Olympic special edition S7 Edge in the end of July 2016 at MOA. I still love using Samsung/Android! So please help me love Samsung/Android longer! Sincerely. — Clara

Solution: Hi Clara. This problem has been observed with some older Galaxy S phones but there is no official Samsung solution so it’s either remains unreported to Samsung, or that it happens only in few isolated cases. The possible causes for this issue can include:

a battery bug

a conflict coming from incompatible third party app

Unknown software glitch

S7 battery calibration

The first workaround that you want to try in case is battery recalibration. This simple procedure will help the operating system read battery levels correctly. At times, Android may get confused in detecting the remaining battery power so it may lead to premature shut downs even though there’s still more than enough power that remains. To rectify this, calibrating the battery must be done. Here’s how it’s done:

Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.

Turn the phone on again and let it turn itself off.

Charge the phone without turning it back on.

Wait until the battery says it fully charged to 100%

Unplug the charger and turn the phone on.

If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.

Unplug the charger the turn the phone on again.

Use the phone until you drain the battery down to 0.

Repeat the cycle once.

Observe in safe mode

In the event that the issue may be caused by incompatible or problematic third party app, you want to boot the phone in safe mode. Safe mode prevents third party apps and services from loading so it’s a good method to use. Due to the nature of the problem, you want to observe the phone while in safe mode for at least 48 hours. This should give you enough time to see any difference in phone behavior. If the problem won’t happen again while safe mode is enabled, that’s a sign that one of installed third party apps is problematic. The thing with safe mode is that it won’t tell you what app exactly is causing a problem. You must identify it yourself by 1.) removing third party apps individually, and, 2.) observing if the problem remains after every uninstallation. This is the only effective way to identify the culprit app.

To boot the phone in safe mode, follow these steps:

Turn your Galaxy S7 off.

Press and hold the Power button.

Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.

Continue holding the button until the phone finishes rebooting.

Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

Restore all software settings to default

Should the issue remains even when the phone is booted to safe mode, the problem may be on the OS level. Try doing a factory reset to wipe all user data and restore all software settings to default. Here’s how to do it:

Turn off your Samsung Galaxy S7.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’

Once highlighted, you may press the Power key to select it.

Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.

Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

The phone will now reboot longer than usual.

Contact Samsung or your carrier for replacement

As in all other Android devices, factory reset is the ultimate software troubleshooting step that you can do. Alright, may be not the ultimate as there are other procedures that you can still do but all of them requires more advanced steps and greatly put the device at risk of being permanently damaged. Such other procedures include flashing stock/custom firmware. Doing them has the same chance of success rate with factory reset though so if factory reset won’t do anything at all, most probably these “more advanced” software troubleshooting may not help as well. In this case, we suggest that you let Samsung or your carrier know of the issue so they can assessed the situation. Most of the time they will recommend a unit replacement so you must take it.

Problem #3: Galaxy S7 won’t respond and screen turns black

I’m having the same issue as Rick and pressing the volume down and power button doesn’t help. It’s not responding.

“Troubleshoot a Samsung Galaxy S7 that’s not responding: Hello TDG. My new S7 just won’t respond when I try to turn it on. Here’s what actually happened. Last night, I left my phone on the table beside my bed with 76% battery left. I didn’t charge it because I know it would take just around 5% to get the phone through the night without using it. When I woke up, however, the screen is black and when I attempted to turn it on, it didn’t respond. So, I thought that for some reason the battery got drained. I tried charging it but those charging indicators won’t also turn on. Should I have it repaired? What’s the problem with it? Help me please. — Rick” — Shavii1995

Solution: Hi Shavii1995. For Samsung phones with unremovable battery pack, the usual battery pull is obviously not possible. Samsung designed a a way instead by allowing a user to press and hold Volume Down and Power buttons together for at least 10 seconds to simulate the effect of a physical battery pull. If pressing the Volume Down and Home keys don’t lead to positive result, you should then try to boot the phone to different modes. Rebooting the phone to different modes uses different hardware button combinations so one of them should work for you. Below are the steps:

Boot in Recovery mode:

Charge the phone for at least 30 minutes.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’

You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

Charge the phone for at least 30 minutes.

Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.

Wait until the Download screen appears.

If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.

Use Google to look for a guide on how to do it.

Boot in safe mode:

Charge the phone for at least 30 minutes.

Press and hold the Power button.

Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.

Continue holding the button until the phone finishes rebooting.

Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem #4: Galaxy S7 keeps crashing and stuck in black screen

My Galaxy S7, which is only 2-3 months old, won’t turn on. It lets me reset the phone in safe mode a few times but kept crashing before I could do anything whilst it turned on and now it is stuck with the black screen. The blue light still on at the top, phone with plenty of charge as it was at 80% before it crashed and I’ve left it on charge several times since it crashed. It won’t let me restart the phone in any way, no matter what buttons I am pressing. If you could please help me as it hasn’t had any problems till now and I don’t really want to have to take it back to the store. Thanks. — Nick

Solution: Hi Nick. We don’t know the history of your phone so there’s nothing much that we can offer you. If the phone is totally unresponsive at this time and booting to different modes does not help at all, there may an unknown hardware malfunction behind this trouble. If your phone was accidentally dropped or exposed to water or heat, stop hoping for a software miracle; no amount of software troubleshooting/solutions can help youi. Bring the phone to a repair shop or to the store so it can be repaired or replaced.

Hi, I just bought an S7, and tried moving the SIM card with 20GB of music from my Note 3 to the S7. While the S7 can see all the .wav files on the SIM card, it a) can’t play them, and b) somehow can’t see the Artist or Album names (it can see the song names). I copied all of these songs from my computer to my Note 3 at some point in the past (and presumably, when it asked me if it should convert them to the format that works best on my phone, I said yes). The songs play just fine on the Note 3, and they do display Artist and Album name. But on the S7, they won’t play and you can’t see Artist or Album name. Do I have any option other than to delete them and re-load them from my computer (which will presumably send them over in the format that works best for THIS phone)? I’m trying to avoid doing that as it can take me a while to go through all my music and copy over what I want. — Johnwilen

Solution: Hi Johnwilen. First of all, we assume that when you say SIM card, you’re actually referring to an SD card.

Secondly, yes, you need to copy the music files from the computer to your S7 in order for all necessary details to be moved over. Some metadata and other details may not have been copied when you move files from the Note 3 to your S7. There’s no system that can help you check whatever data were not transferred so your best option right now is to move files directly from your PC to the S7.

Problem #6: Galaxy S7 Edge not showing correct internal storage space

Hi Friends. I got a weird problem with my Samsung S7 Edge. I have an 128 GB SD card. All my photos of 7 GB moved to SD, but though the internal memory is showing up with 7GB usage of photos, when i open that, it’s showing no photos. The internal space occupied is showing as 7GB of photos. When i unmounted my SD card that time, also it is showing in this weird way.

This problem not only happens with photos. All my videos and audios as well. Totally, my 30GB is used in this weird way when the actual memory used internally is only about 10GB. I hope you understand my problem. Guys please help me out of this. — Srujith

Solution: Hi Srujith. There may be an unknown bug either in the operating system or in the SD card that causes this problem. The first thing that you want to do is to reformat the SD card using your S7 to ensure that it’s being read properly. Here are the steps:

Create a back up of your important files to another device.

From home, tap Apps all apps icon > Settings settings app icon.

Tap Storage storage settings icon.

Tap SD Card > Format.

Tap Format to confirm.

Once you’ve reformatted the SD card move all your files to it again and observe how everything works. If the issue remains, do a factory reset. This procedure should clear all user data and eliminate the bug that causes the problem.
